Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pyrolysis gasification incineration process for small-scale rural garbage, which solves the problem that the current rural garbage has high humidity, and how many garbage incineration stations divide the garbage into three steps of drying, pyrolysis gasification, and melting and burning. Completion, complex process, or direct combustion without drying, or direct combustion without drying pyrolysis; and it is easy to cause secondary pollution to the environment

Abstract

The invention discloses a desalination cultivation method for juvenile crabs which comprises the following steps: S1, firstly, selecting a culture pond, building a sunshade blocking piece at the upper part of a pond body, and putting floating objects for shielding sunlight into the pond body for juvenile crab growth; S2, equipment application: adding oxygenation equipment and water pumping equipment into the culture pond; S3, region division: dividing the culture pond into four sections for juvenile crab activity, wherein the four sections are located at the four corners of the culture pond respectively, and oxygenation equipment is arranged in each of the four activity sections; S4, juvenile crab selection: wherein the selected juvenile crabs have the following characteristics that the juvenile crabs are normal in color and glossy, the juvenile crabs are vigorous, the surfaces of juvenile shells are intact and free of collision, pits and protrusions, the crab legs are not incomplete, and the sizes and specifications are uniform; S5, pond water planning: wherein the salinity of the pond water for the first time is 30. According to the desalination cultivation method for juvenile crabs, the survival rate of the juvenile crabs is increased, desalination cultivation of the juvenile crabs is facilitated, and growth of the juvenile crabs is facilitated.

Description

technical field [0001] The invention relates to the technical field of crab seedling cultivation, in particular to a desalination cultivation method of crab seedlings. Background technique [0002] Crabs are the main marine cultured crabs in the southern provinces of my country. In recent years, blue crab farming has developed vigorously. The breeding area in my country has reached 31,000 hectares, with an annual output of 116,000 tons (China Fishery Statistical Yearbook, 2010). It has developed into an important mariculture industry in my country. Scylla aquaculture is of great significance for enriching marine aquaculture species in my country, promoting the adjustment of regional aquaculture structure, and improving the ecological conditions of the aquaculture environment. Spring is a critical period for crab farming, and the selection and distribution of crab seedlings determine the output and benefits of year-end farming. When crab seedlings are currently released, cr...
